About

​​Enlarged project mapThe South Yamhill River Bridge was built in 1951 and is approaching the end of its functional lifespan with many components that are in poor condition. 

This project will replace the South Yamhill River Bridge on a busy route into and out of McMinnville with a daily average daily traffic volume of 16,000 vehicles. ​​The new bridge will replace the existing 35 foot wide bridge with a wider 48 foot wide bridge. This will better accommodate large trucks, bicycles and pedestrians. 

project alerts iconFor construction staging, a detour bridge will be placed to the west of the existing bridge. Traffic will be detoured while the existing bridge is removed and the new one is constructed in the same location.
 

Schedule

Design through 2021.
Construction to begin in 2021 and estimated to last four years.

2021

  • We will build a temporary diversion bridge to the west of the existing bridge. 

2022

  • We will build the connections from the road to the temporary diversion bridge. Our crews will mostly be working off of the existing roadway. 
  • After we build the connections, we will route traffic and pedestrians to the diversion bridge, remove the existing bridge and construct the new bridge. 

2023 - 2024

  • We will complete the construction of the new bridge and rebuild connections to the roadway.
  • We will construct a sanitary sewer line along Three Mile Lane.
    • During this time expect delays and road closures to a single lane of traffic controlled by flaggers.
